A novel de novo splice-site mutation in the COL7A1 gene in dominant dystrophic epidermolysis bullosa (DDEB): specific exon skipping could be a prognostic factor for DDEB pruriginosa.

Abstract excerpt

We report a Japanese infant who had a novel de novo splice-site mutation in the COL7A1 gene, which resulted in in-frame exon 87 skipping. Very interestingly, most of the previously reported cases with the same exon skipping presented as dystrophic epidermolysis bullosa (DEB) pruriginosa. The proband in this study showed an extremely mild clinical phenotype, with no nail dystrophy, pruritus or prurigo-like...
